摘要：
In this paper, non-Darcy free convection boundary layer flow along an isothermal vertical plate embedded in a thermally stratified fluid saturated porous medium has been described. The main aim in the analysis is to study the effect of stratification on non-Darcian free convection flow and heat transfer. The solutions are obtained by perturbation technique and the resulting ordinary differential equations are solved numerically. It is found that the heat transfer is significantly affected by the modified Grashof number and the stratification parameter.
